Sold some of coins when it touched $2800 few days back and people who didn't sold at that price hoping that it will go much higher would be surely regretting at a moment as that was the best time to sell off some off your coins in order to make good profits and even the current price is to good to sell your coins if you have bought them at lower price in the past as waiting too long can be really risky as you never know how the price will behave in coming days.
